It will lead you to our on-line purchase system, and you can pay via a credit card. Then we will send you a serial number.

After the purchase is done successfully, you could get a transaction ID marked in yellow in the confirmation webpage, please use that transaction ID to get the serial number by visiting the following link http://www.bluesoleil.com/support/index.asp?topic=findsn.
Please notice that this transaction ID is a seller transaction ID and you could use it to get the serial number from this system, after the purchase is done, you will receive a confirmation email from PAYPAL including another transaction ID that is a buyer transaction ID and you can not use the buyer transaction ID to get serial number from this system

BlueSoleil version 10 needs serial number to activate and it is not free.

Minor versions (1.1, 1.2 etc.) are free to registered customers because they contain only small functional improvements and defect fixes>>

Major versions (7.0, 8.0 etc.) are chargeable because they represent significant upgrades in functionality that require investment of time, money and resources to design, develop, test, document and publish the new features. We will ensure that customers get value for money and a well-rounded new product for each major version.http://www.bluesoleil.com/shop/Intro.aspx?topic=Upgrade_Policy>

It's a prevalent confusion for users.

We do have an ecommerce site on www.BlueSoleil.com to sell dongles with brand name "BlueSoleil" and these dongles are well checked and licensed one by one.

Bluetooth passkey is used in authentication procedure for Bluetooth security purpose. When remote device connects to your computer, he has to offer the same Bluetooth passkey as what you input such as "1234". If the Bluetooth passkeys from two sides are the same, connection can be set up. A paired relationship is established on both sides. There is no need to input passkey for the next time of connection. Either side can delete the paired relationship.
In addition, for those Bluetooth devices that don't have input configuration such as headset, you can only input the passkey which is a default on the computer side, you can generally find it on the cover of the package for your Bluetooth device or you can check the user manual of your Bluetooth device.
